Each disable bit in the HcInterruptDisable register corresponds to an associated interrupt
bit in the HcInterruptStatus register. The HcInterruptDisable register is coupled with the
HcInterruptEnable register. Therefore, writing logic 1 to a bit in this register clears the
corresponding bit in the HcInterruptEnable register, whereas writing logic 0 to a bit in this
register leaves the corresponding bit in the HcInterruptEnable register unchanged. On a
read, the current value of the HcInterruptEnable register is returned.
The register contains 4 bytes, and the bit allocation is given in
Description
Start-of-Frame:
0 — Ignore
1 — Enables interrupt generation because of Start-of-Frame.
HcDoneHead Write-back:
0 — Ignore
1 — Enables interrupt generation because of HcDoneHead write-back.
Scheduling Overrun:
0 — Ignore
1 — Enables interrupt generation because of scheduling overrun.
